OMC Evinrude Johnson Sensor Assembly

The OMC Evinrude Johnson Sensor Assembly, part number 584491 (also listed as 0584491), is an OEM air temperature sensor designed for specific Evinrude and Johnson outboard motors. This sensor plays a crucial role in monitoring the intake air temperature, allowing the engine's electronic control module (ECM) to adjust fuel delivery and ignition timing for optimal performance and efficiency.

Key Features:

• Function: Measures the temperature of incoming air to the engine, enabling precise adjustments to the fuel-air mixture.

• Compatibility: Commonly used in Evinrude Ficht models, including 90hp, 115hp, 150hp, and 175hp engines from the late 1990s to early 2000s.

• OEM Quality: Manufactured to original equipment specifications, ensuring reliable performance and compatibility.

• Installation: Typically mounted on the intake manifold and secured with two bolts.

This sensor is essential for maintaining efficient engine operation, especially in varying environmental conditions. If you're experiencing issues related to fuel efficiency or engine performance, replacing a faulty air temperature sensor like the 584491 may resolve the problem.
